Garrett McNamara waits for a wave during a surf session at Praia do Norte in Nazare on Wednesday.. McNamara currently holds the world record for the biggest wave surfed after riding a 78-foot (23.77-meter) breaker in Nazare, central Portugal, on Nov. 1, 2011, but on Monday was thought to have gone better at the same location. The 45-year-old from Hawaii was cautious about his exploit, though, telling reporters that he had "no idea" about the size of the wave and that his partner Kealii Mamala may even have set the new global benchmark.
